  1. Best answer
    500w.

    Get a unit from ANtec, XFX, Corsair, or Seasonic.

    The xfx 550w unit is what I would recommend.

    Thank you for the recommendation but I would just like to ask if it is worth paying more for the "Gold Certified" PSU (Which costs about $80 to $100+)
    or should I stick to the PSU that are stated to be "Bronze certified" or isn't stated about being certified, which is quite cheaper? I am very concerned about quality and to be honest, I am paranoid about buying lousy parts.

    Thanks again for the help :)
  3. Anything from the companies I listed will be perfectly fine. They are top of the line.

    Never buy anything that isn't at least bronze certified.
